my baby is 4 months now and here is the breakdown of cost expenditure for her:
1) cost of labor is RM8k ++ plus RM1k ++ due to her jaundice
2) during confinement, we stay together in my MIL place. i just only pay her some money as token of appreciation around RM500 if I'm not mistaken
3) baby is fully breastfeeding so we do save a lot on that but wife have to sacrifice her time to pump and all but so far so good till now
4) since she is 4 months now, we will start to give her to eat some food on top of her breastmilk (didn't calculate that tho since we didn't start yet)
5) day time we send our baby to my MIL and i do give her some money as a "fee" even that she doesn't ask for it but i think it is something for her
6) clothes wise we have to start buy a new sets for her since most of her clothes has no longer fit and AFAIK, baby clothes is even more expensive than adults. so we allocated RM200 for that for every 3 months for now
7) diapers - any brand suits her. so we spend like RM200 for a month for that
8) milk - we are looking at fully breastfeeding her till 2 years old and not thinking of adding formula. after all mum's milk is the best milk
9) RM100 is allocated every month for her savings (education / car / home etc) this amount have to increase as the time goes by due to the cost of living now
10) we're lucky because of most of the check up are bare by wife's company but till then RM100 still been put into her "insurance" savings, just in case
all in all, starting a family is not easy especially in these times but nor its difficult if u know how to manage it well. i'm blessed coz my MIL is working from home mum and she is willing to take care of my baby. good luck to u if u are thinking of starting your own, and believe me, having your own family is fun and exciting journey all the way!
